Buildings are machines that can be constructed by the Engineer using his Build Tool. The five available buildings are:

Buildings
Engineers require Metal to create, upgrade and repair buildings.
Like players, buildings have health, and are destroyed when their health is reduced to zero (see Destruction below). A building can be deliberately destroyed by using the Destroy Menu. Buildings capable of being upgraded receive an additional 20% to their health each time they are upgraded. Critical hits do not cause extra damage to buildings. Weapons also do not suffer from damage drop off on buildings; regardless of distance, every hit does the same amount of damage (excluding splash damage). Buildings have visual effects to indicate their damage; slightly damaged buildings will emit smoke and sparks, and severely damaged buildings will appear to be on fire. The Spy can disable and slowly damage buildings over time using his Electro Sapper. The Demolish Tool cannot be used to destroy buildings that are in the process of being sapped.
Buildings are erected automatically after being deployed, but can be built twice as fast by hitting them repeatedly with the Engineer's Wrench during construction and a further 30% faster by having the Jag as your wrench. Having more than one Engineer hitting a building under construction stacks the effect. Demolishing unused buildings is useful for recollecting metal, as they will explode into broken metal pieces upon destruction.
Once a standard Sentry Gun, Dispenser, or Teleporter has been completely built, the Engineer can spend metal to repair, resupply, and upgrade them by hitting them again with his Wrench. Metal priority goes to repair first, then to resupply, and finally to upgrades, with limits to how much metal can go into each task with each strike of the Wrench. You also use the Wrench to clear your buildings of Electro Sappers; they take two hits to remove. Friendly Pyros wielding Homewreckers can remove Sappers with a single hit.
All buildings are able to be walked through by an Engineer's teammates, however, they will act solid towards the Engineer himself, allowing him to stand on top of his own buildings. Buildings also act solid for enemies, including enemy Spies. In water, buildings function normally; however, a Sentry Gun that is fully immersed in water will not target enemies that are on dry land, and vice versa.

Note: All build time is in seconds. Levels 2 and 3 Sentry Gun build times are longer because upgrade animations cannot be skipped or hastened.

HUD
The Building HUD provides at-a-glance information on the Engineer's buildings and any enemy Spy's Electro Sappers. The status of different aspects of the building is indicated by an icon.
| Icon | Description |
|---|---|
|
A number indicating the number of kills a sentry has followed by the number of assists in brackets (Sentry Guns only). |
|
An indicator bar representing the percentage left of ammunition (Sentry Gun) or metal reserves (Dispenser). |
|
An indicator bar representing the percentage of the building upgrade progress (Levels 1 and 2 only). |
|
An indicator bar representing the percentage left of rocket reserves (Level 3 Sentry only). |
|
A number indicating the number of teleports a Teleporter entrance has provided. Transforms to a recharge progress bar after a teleport. |
Hauling
Buildings can be packed up and moved by their owners by pressing the alternate fire button while looking at and standing next to them. The operation is instantaneous, and the Engineer will appear carrying the building's toolbox on his shoulder to all players, while from his first-person perspective he will still carry the toolbox as a normal building construction. Damaged buildings can be packed up, but not those currently under the Electro Sapper's effect. A building is capable of being hauled when a gray tab is displayed alongside the building's name on the interface (see right). In addition to an icon for the building and a hand, the tab also displays which which key or mouse button alternate fire is currently bound to.
It's possible to haul a maximum of one building at a time, and doing so will sensibly reduce the Engineer speed to 75% (225v), slightly slower than a Heavy, regardless of type and/or level of the building. Additionally, the Engineer won't be able to switch to any weapon or item until the building is redeployed. It's still possible to use his own Teleporters (unless he is hauling the entrance or exit to his own Teleporters) and those of friendly Engineers.
While hauling a building if the Engineer is killed the building is destroyed along with him. A special kill icon representing a toolbox will be shown alongside the Engineer's.
Redeploying a building is similar to a normal construction, except that the building will construct itself at twice the normal rate, and the Engineer can still speed up the process even further. Higher level buildings will have to cycle through all their upgrade animations before becoming operative, and cannot be packed up again until ready. Damaged buildings retain their health at the moment they were packed, and also cannot be repaired until operative again.
The three phases of building redeployment (packing, hauling and redeploying), are accompanied by specific responses.
This mechanic allows for redeployment without having to completely reconstruct the building, thus saving metal and time, and also preserving any score tallies a building may have.
Destruction
A building can be by destroyed by his owner using the Demolish Tool or by an enemy using any weapon, including the Electro Sapper. A building can also be destroyed if an Engineer is carrying a building and a player kills the Engineer. A destruction is worth one point to the destroyer and is recorded on the player's scoreboard. A destruction cannot be assisted, unless the building has been sapped previously by a Spy; the Spy will then be awarded the assist point.
Destruction points cannot be awarded to Engineers who destroy their own buildings. Furthermore, destructions will not count during the Setup Phase. However the destruction still occurs in game, and any associated effects, such as Frontier Justice's Revenge Crits, are triggered.
When a building is destroyed, the Engineer responds with one of three responses, alerting his nearby teammates.
